Title: Process of cutting and apparatus for its application
IPC: A41H1/02
Filed: 1923-01-16
Abstract: 192,380. Orlandi, A. Servaglia-. Jan. 24, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Clinometers. - In cutting out garments and patterns the slope and length of the shoulders are determined by an instrument 3, Fig. 1, and these measurements are employed in making the pattern. The instrument employed may have a pendulum cooperating with a pointer 4 moving over a dial 3 divided into degrees, and also a scale 2 of length and a push button 5 for steadying the pendulum and pointer. In drawing the pattern, a point O, Fig. 2, is taken and rectangular axes O x, O y drawn. A line 0 A is drawn equal in length to that measured on the scale and having the required angle x O A of the shoulder slope. The points B and C are marked to correspond respectively to the waist and bottom of the garment,. and D and E are correspondingly positioned for the back seam O D E. At the height Z of the sleeve hole a distance is measured proportionate to the breadth of the back and the line F G drawn parallel to 0 y. The difference between this length and a little less than the sleeve hole radius r determines the centre M of the sleeve hole, which is also at a distance from the point A of about three centimetres in excess of the length r. The length r is obtained by calculation from certain trunk measurements. The point A is joined to the circle of radius r at a tangent. The dot and dash lines represent the front half portion of the garment and the full lines the back half portion. A circle is described from the point 0 as centre with a radius equal to one quarter the neck hole periphery. The point H is on a line parallel to the axis of x and at a distance of two centimetres therefrom. The line H I is drawn parallel to and equal in length to A o. The line N P is drawn parallel to 0 x and at a distance of one third of half the sleeve hole. A supplementary portion determined by the line v V varies in size with the position of the buttons. In place of the apparatus shown, an apparatus may be used in which three hinged members form a triangle and co-operate with a level.

Filed: 1973-01-05
Abstract: 1372625 Axial-flow fans WOODS OF COLCHESTER Ltd 5 Jan 1973 [12 Jan 1972] 1551/72 Heading F1C An impeller for a variable-pitch axial-flow fan comprises a hollow hub formed with openings from which the blades extend, each blade carrying, within the hub, a flange extending radially outwards with respect to the blade axis, a thrust bearing being interposed between the flange and the inner surface of the hub around the opening, and annular spring means act between the outer surface of the hub around the opening and a co-operating surface of the blade so as to preload the thrust bearing when the impeller is stationary, and one or more annular washers located between the spring means and the hub are of such mass that on rotation of the impeller at a certain speed below its normal operating speed the mass of the washer or washers compresses the spring means under centrifugal force to an extent which eliminates the pre-loading of the bearing. A convoluted spring washer 12 (or one or more Belleville spring washers) acts between the circular root 5 of each blade 3 and an annular flange 11 on the impeller hub 1 to urge the blade outwardly and thereby pre-load the bearing 10 to avoid noise and impact damage at low speeds due to play in the bearing. A weight in the form of one or more washers 18 is interposed between the spring washer 12 and the flange 11. When the impeller has reached a certain speed below its operating speed, the centrifugal force on the washer 18 overcomes the spring force of the washer 12 and lifts the washer 18 clear of the flange 11 as shown, thereby removing the preload. One or more counterweights 17 are provided to oppose the inherent turning movement produced on the blade 3 by centrifugal forces.
